I love this topic!!! I had Promax Mill and blend the choke horn of my 350 center, and they said it increased the CFM in excess of the +50 CFM that I anaticipated. If I recall it was closer to +75 CFM. Either way, that mod combined with some of their other goodies worked well enough to feed my 493" stroker to the tune of 681 HP at 5500 rpm.

I remained curious as to how much more HP could be tweeked out of a stroker motor with a deep ported aluminum sixpack intake with the same thing done to a 500 CFM carb.

I needed my motor to have some street manners, so it is camed accordingly with a hydraulic cam. I know if I put the right mechanical roller in there it would have broken into the 700+ HP range...How much longer are you guys going to wait until one of you just has to take a nice stroker motor to the limit with a Holley induction and a deep ported Edlebrock intake? That hyped-up Six Shooter pales in comparison in this neck of the woods! Inquiring minds want to know.
